In this article I am going to share the Secrets of Structural Engineering which you will not find in any books even Structural Engineers will not share. Structural Design specially Reinforced Cement Concrete Structures (RCC Structures) we need to check against various critical factors or conditions.
After checking for all such conditions like Shear Stress, Bending Moment, Axial Force and so on, there will be one most important critical parameter on which the main structural geometry of the Slab, Beam, Column, Foundation will be done for determining its Depth, Width, or the Cross-Section in general.
A RESIDENTIAL BUILDING STRUCTURE ONGOING
What I will share with you now only comes from experience after doing enough Structural Design for RCC Structures. Hence, you must surely look for this parameters very precisely along with all others.
|Sl. No.||Type of Structure||Governing Parameter|
|1||Continuous and Discontinuous Slabs for Residential Class Loading||Deflection|
|2||Discontinuous Slab of Commercial, Institutional etc. Loading Class||Mid Span Positive Bending Moment|
|3||Continuous Slab of Commercial, Institutional etc. Loading Class||Continuous Edge Maximum Negative Bending Moment|
|4||Single Span Beam||Maximum Positive Span Moment|
|5||Multi-Span Beam||Maximum Negative Support Moment|
|6||Interior Short Column||Axial Force|
|7||Exterior Short Column of General Residential Loading Class Building||Axial Force|
|8||Exterior Short Column of High Rise Residential Loading Class Building or Commercial/ Institutional Building||Combination of Column Moments and Axial Force|
|9||Long Column||Combination of Slenderness Ratio and Axial Force|
|10||Isolated Column Footing||Shear Stress both One Way and Punching Shear|
|11||Combined/Strap/Raft/Mat Column Footing||Bending Moments -for Single span Span Moment and for Multi-Span Support Moment|
|12||Stair||Span Positive Bending Moment|
|13||Lintel||Span Positive Bending Moment|
I hope this article will boost your Structural Design Skill and you will be now able to perform Structural Design much more quicker than you used to. Again this will help you at site for spot Structural Design decision with only a calculator in hand to take up the job and have a fair idea about the final structural design results.
